There are 12 points in a plane of which 5 are collinear. Except these five points no three are collinear, then

There are 20 points in a plane of which 5 are collinear and no three of the points are collinear unless all the three are from these 5 points. Find the number of different lines formed.

There are 20 points in a plane of which 5 are collinear and no three of the points are collinear unless all the three are from these 5 points. Find the number of different straight lines passing through these points

There are 20 points in a plane of which 5 are collinear and no three of the points are collinear unless all the three are from these 5 points. Find the number of different triangles fromed by joining these points

There are 10 points in a plane of which 4 are collinear. No three of the remaining 6 points are collinear. How many different straightlines can be drawn by joining them?

There are 20 points in a plane out of which 7 points are collinear and no three of the points are collinear unless all the three are from these 7 points. Find the number of different straight lines.

There are 16 points in a plane of which 6 points are collinear and no other 3 points are collinear.Then the number of quadrilaterals that can be formed by joining these points is

There are 16 points in a plane of which 6 points are collinear and no other 3 points are collinear.Then the number of quadrilaterals that can be formed by joining these points is

The are m points in a plane out of which p points are collinear and no three of the points are collinear unless all the three are from these p points. Find the number of different triangles formed by joining these points (by line segments).
